11.1 ISE - Back-Annotate Pin Locations results in: "ERROR: you must set the property 'Target UCF File Name'"

Description

Keywords: constraints, place and route, place & route, PAR, UCF

I have correctly added my UCF file to the Project Navigator project, but when running the Back-Annotate Pin Locations process, I receive the following error:

"Started : "Back-Annotate Pin Locations".
ERROR: you must set the property 'Target UCF File Name'."

Solution

Project Navigator (ISE 10.1 and later) allows a project to have multiple User Constraint Files (UCFs). In order for the Back-Annotate Pin Locations process to know which UCF to annotate the pin constraints to, the "Target UCF File Name" needs to be set. This property is located by right-clicking the Back-Annotate Pin Locations process and selecting Properties.
